"I had contracted dragon pox shortly before arriving at school, and while I was no longer contagious, my pockmarked visage and greenish hue did not encourage many to approach me."
—Description of Dragon Pox[src]
Dragon Pox[1] is a potentially fatal contagious disease that occurs in wizards and witches. Its symptoms are presumably similar to Muggle illnesses like smallpox and chicken pox. However, in addition to leaving the victim's skin pockmarked, dragon pox causes a lasting greenish tinge.[2] Simpler cases present with a green-and-purple rash between the toes and sparks coming out of the nostrils when the patient sneezes.[3]


"Occasionally they would catch snatches of advice on how to treat dragonpox, and once a few bars of “A Cauldron Full of Hot, Strong Love."
Wizarding Wireless Network[src]

The first cases of Dragon Pox were wizards working closely with Peruvian Vipertooths;[4] the first person known to have died from dragon pox was Chauncey Oldridge in 1379.[5] Two centuries earlier (in the 1100s) Gunhilda Kneen was recorded as having to forgo playing Chaser in a Quidditch match when she came down with a "touch" of the sickness.[6]

Gunhilda of Gorsemoor developed a cure for dragon pox,[7] but the disease has not been completely eradicated. It is still treated by the Magical Bugs ward at St Mungo's on the second floor.[8] Perhaps to address this, Albus Dumbledore possibly worked on his own version of the cure around 1991.[9] Elphias Doge got dragon pox shortly before he started at Hogwarts School of Witchcraft and Wizardry in September 1892.[2]

Elderly patients are apparently more susceptible to dragon pox than younger ones. Minister for Magic Eldritch Diggory died of it in office in 1747.[10] Others who have died of it include: Abraxas Malfoy, and Fleamont and Euphemia Potter.[11] They died of it recently, in the second half of the 20th century.

Howland Coopey writes to the Daily Prophet with symptoms that Professor Helbert Spleen diagnoses as Dragon Pox, although he does state that it will go away of its own accord, rather than recommending that Mr Coopey go to St Mungo’s to get the Dragon Pox cure.[12]

The Moldovan National Quidditch team could not participate in the 2014 Quidditch World Cup due to an outbreak of Dragon Pox at their training camp, leaving their supporters devastated.[1]
